OIL-BURNER.

Specification of Letters Patent.

Patented June 15, 1915.

Application filed m 10, 1912. 7 Serial No. 708,599.

To all whom it may concern:

Be it known that we,"Wn.LrAM-R. J nevons and ARNOLD R. Wrrrrmnnn,citizens of the United States, residing at Cleveland, in the county ofCuyahogaand State of Ohio, have invented a certain new and'us'efulImprovement in Oil-Burners, of which the following is a full, clear, andexact description, re erence beinghad to the accompanyingdrawings. I

This invention relates to oil burners of the type wherein there is apair of Wick tubes and an air distributer havin a spreader extendingacross and spaced om the top of the wick tubes, the inner Wick tubebeing provided with a seat for the distributer, formed preferably as aspanner comprising an outer and an inner ring'and connected by arms, theinner ring havin a central guide opening for the spindle which dependsfrom the central portion of the distributer.

As heretofore constructed, the distributor has been supported by meansof a spreader of the character hereinbefore described having avertically extending annular flange at its periphery, which flange hasbeen secured to the inner tube by means of solder. In operation, theparts are liable to be so subjected to heat as to melt the solder, withthe result that the support for the distributer'will become dislodged,leaving the distributer with no means for supporting and centering thesame. In burners of this type it is exceedingly important that thespread-. ers shall be at a predetermined distance from the tops of thewick tubes. Should the support for the distributor, of which thespreader forms a part, become'loosened or have its position altered in avertical direction, the distance between the spreader and the, tops ofthe wick tubes would be correspondingly affected with the result thatthe burner will not properly function.

It is the purpose of this invention to provide an extremely efiicient,though simple, means whereby the distributer support or spanner may beanchored securely in place 'within the inner wick tube without anyliability to become dislodged.

\Vith the foregoing objects in view the invention may be defined furtherand more generally as consisting of the combinations of elementsembodied in the claims hereto annexed and illustrated in the drawingsforming a part hereof, wherein- Figure 1 represents a vertical sectionalview taken through a portion of the oil stove burner, illustrating themanner, of supporting the spanner within the inner wick tube; Fig. 2represents a transverse sectional view taken through the inner, wicktube of the aforesaid burner and showing the projections whereby thedistributer support is anchored in place, the view being taken onapproximately the line 2-2 of Fig. 3; Fig.

3 represents an elevation of the portion of";

theinner wick tube which is provided with 3 the anchoring projections,and Fi 4 an enlarged sectional detail illustrating the.

manner in which the outer edge of the dis- 1 tributer support is held inplace.

Describingthe various parts illustrated herein by means of referencecharacters, 1

re resents the inner and 2 the outer wick.

tu e of a burner, said tubes having in terposed therebetween a wick 3,which may .be raised and lowered by means of a wick raising shaft havingan operating handle 4. Within the interior of the inner wick tube thereis located an air distributor and spreader, which is, of the type shownin the atent to Jeavons No. 871,593 issuedNovem- 7 er 19, 1907. Thiscombined air distributor and-spreader comprises a ring 5 havingperforations at the upper end thereof, the ring being connectedto a neck6, to the top of which are attached the spreader plates 7 and 8. Thespindle 9 is connected to the upper spreader plate and depends centrallytherefrom within the neck 6 and ring 5. Depending from the bottom of thedistributer and spreader is a locking device having dependinghorizontalshoulders 11 which normally extend beneath the arms 12 of the spider.

The vertical movement of the distributer.

sol

therein by means of an up er and a lower series of inwardly extendingprojections ressed from the body of the wick tube.

he upper series of projections 16 and the lower series of projections 17are preferably formed'in the wick tube after the spider is inserted inplace, the two series being vertically spaced to receive snuglytherebetween the outer edge of the supporting ring or plate 14 7 (seeparticularly Fig. 4). In forming these projections in the light sheetmetal of which the inner wick tube is composed, there is great dangerthat the metal will be so drawn or stretched as to afford an lns'ecuresupport for the distributer support, if, in fact, the support is notallowed to drop by reason of the stretching action referred to. To avoidstretchin the metal to this extent and at the same time to provide averysecure anchoring means for the distributer support, the projections ineach series are spaced laterally a considerable distance apart,greaterthan the width of a projection (or the width of the recess caused byforming a projection)and the projections of one series are staggeredwith respect to those of the other series. This arrangement will beclear from Fi 3. The projections may be conveniently ormed by means oftwo toothed wheels placed side by side on ,a common arbor, or by adouble toothed wheel, the teeth bein of such width and so spaced as toprovide t e arrangement of projections shown in the drawings.

The anchoring means described herein is one obtainable in an extremelysimple manner and may be produced at very small expense. It has,however, been found to be extremely efiicient in use.

Having thus described our invention, what we claim is 1. In an oilburner, the combination, with a cylindrical metal tube adapted to formthe internal support for a circular wick, of a supporting member locatedwithin said tube and engaging the walls thereof, said tube beingprovided with an u per and a lower series of circularly spacedprojections extending inwardly rem the inner wall there- -of above andbelow the outer edge of said supporting member.

. circularly 2. In an oil burner, the combination, with a cylindricalmetal tube adapted to form the internal support for a wick, of asupporting member located within said tube and having its outer edgeabutting against formed by pressing form the internal support for awick, of

a supporting member located within said tube and having its outer edgeabutting against the interior wall of said tube, said tube having anupper and a lower series of spaced internal projections formed byembossing the metal of the tube andreeeiving between them the outer edgee of said supporting member, the distance between adjacent projectionsof each series hemg greater than the width of a projection,

and the projections of oneseries being staggored with respect totliose'of the other semes.

4. In an oil burner, the combination, with a cylindrical metal tubeadapted to form an inner wick' tube, of a supporting member or spannerof substantially the same external diameter as the internal diameter ofsaid spanner, the distance between adjacent projections of each seriesbeing greater than the width of a projection.

In testimony whereof, we hereunto atiix our s gnatures in the. presenceof two wit nesses.
